Coexpression of the AMY1 gene and AMY2 gene (pancreatic type) was observed in most of the lung cancers without hyperamylasemia, lung tissue, and cells scraped from the tracheal epithelium, thyroid, and female genital tract (ovary, fallopian tube, and uterus cervix), while minimal levels of mRNA transcripts of the AMY2 gene were detected in other malignant neoplasms, various normal tissues, and the cultured cell lines.

Nucleotide sequence analysis showed that the amylase expressed in this carcinoid tumor has 13 and 6 amino acid substitutions when compared with salivary amylase (Amy1) and pancreatic amylase (Amy2), respectively.
